DAMASCUS, Sept. 18 (Xinhua) -- An explosive device went off overnight while a convoy of the U.S.-led coalition was passing by in a village in the eastern province of Deir al-Zour, a war monitor reported Friday.
The explosive device exploded while the convoy was passing by in the village of Abriha in the eastern countryside of Deir al-Zour, said the Syrian Observatory for Human Rights.
The explosion left damage with no report on casualties, the UK-based watchdog group added.
Also on Thursday evening, three explosive devices exploded near the al-Omar oil field while a vehicle of the U.S.-backed Syrian Democratic Forces (SDF) was passing by, said the observatory, noting that the explosion left no losses.
At early time on Thursday, a group of unknown armed men opened fire on a patrol of the SDF in the Basira area in Deir al-Zour with no report on casualties.
The opposition activists have repeatedly reported a state of lawlessness in areas controlled by the SDF in the eastern and northeastern Syria. Enditem
